PURPOSE:To provide a freezer lubricant giving excellent seizure resistance and abrasion resistance to synthetic oils by adding a specific diorganophosphorodithioic acid oxymolybdenum sulfide and a specified diorganodithiocarbamic acid oxymolybdenum sulfide in constant amounts to the synthetic oil. CONSTITUTION:The objective lubricant having excellent solubility in Freon solvents not containing chlorine in the molecules is characterized by adding (A) a diorganophosphorodithioic acid oxymolybdenum sulfide of formula I (R is 3-20C hydrocarbon group; 0<=X<=4, 0<=Y<=4, and X+Y=4) and/or (B) a diorganodithiocarbamic acid oxymolybdenum sulfide of formula II (R' is 3-20C hydrocarbon group; 0<=X'<=4, 0<=Y<=4, and X'+Y'=4), the total amount of the components A and B being 0.1-10-wt.%. to a synthetic oil such as a polyoxyalkylene glycol. |
